pub struct OwnedFd { /* private fields */ }
Expand description
An owned file descriptor.
This closes the file descriptor on drop. It is guaranteed that nobody else will close the file descriptor.
This uses repr(transparent)
and has the representation of a host file
descriptor, so it can be used in FFI in places where a file descriptor is
passed as a consumed argument or returned as an owned value, and it never
has the value -1
.
You can use AsFd::as_fd
to obtain a BorrowedFd
.
